FMRI Studies of Visual Categorization in The Human Brain
Alexander Huth, et.al., at the University of California, Berkeley, have demonstrated how five human subjects, each viewing over two hours of movie clips, were each scanned by functional Magnetic Resonance Imaging instruments. Each brain scan recorded blood flow in thousands of individual locations, across their respective brains. Principal components analysis of regularized linear regressions revealed 1700 visual categories of 30,000 locations in cortex. Huth et.al. found highly organized, overlapping maps that occupied over 20% of cortex.

“Your small hands, precisely equal to my own—
only the thumb is larger, longer—in these hands
I could trust the world, or in many hands like these,
handling power-tools or steering-wheel
or touching a human face ...”
—Adrienne Rich (b. 1929)
“Shall quips and sentences and these paper bullets of the brain awe a man from the career of his humor? No, the world must be peopled.”
